How to Winterize Your RV
Keep your RV piping and waterlines safe through harsh Canadian winters with WinterProof™ RV Water System Antifreeze and our BurstGuard™ Guarantee -50˚C. Follow these simple steps to avoid complications and costly repairs:
Lower the trailer slightly with the jack to allow better water flow out of the tank.
Remove the drain plug on the fresh water tank. This plug is fitted as original equipment. Your RV may already come with a drain valve or tap.
Open your kitchen sink taps, bathroom sink, and shower taps to empty all remaining water down the drain. Flush the toilet. If you have an outside shower, remember to drain that too.
Make sure your water heater is off. We don’t want to empty the water heater with the propane on and ignite it.
Drain the water heater. Locate the water heater on the outside of your trailer and open the cover. Pull up the handle on the pressure relief valve to release any pressure.
Re-insert the anode rod after the water heater is empty. It’s a good idea to apply Teflon tape or appropriate fitting compound to the fitting threads to avoid leakage. Re-insert the anode rod and tighten it.
Ensure that the black and grey water tanks are empty. Always empty the black water tank first then the grey water tank.
You want to fill the water lines in the trailer with WinterProof™ RV Water System Antifreeze. However, you do not want any antifreeze to enter the water heater.
Close both the bottom and top valves to prevent WinterProof™ RV Water System Antifreeze from entering the water heater.
Locate the fresh water tank and tube that will allow the pump to suck up antifreeze to winterize the system. If you do not have a suction tube you can purchase a winterizing kit at an RV service center.
Close the valve from the fresh water tank so WinterProof™ RV Water System Antifreeze does not enter and then open the valve to the suction tube.
Turn on your pump for fifteen seconds to let the pump run dry. Don’t overrun your pump when it’s empty.
Turn off all your taps prior to filling the lines with WinterProof™ RV Water System Antifreeze.
Place the suction tube into the jug of WinterProof™ RV Water System Antifreeze and turn on the pump. Exchange antifreeze jugs as they become empty.
Turn on both the cold and hot water taps throughout until green Winterproof™ RV Water System Antifreeze appears. You’ll want about 250 mL (1 cup) of antifreeze to run into the toilet. Open the outside shower to fill this waterline with plumbing antifreeze.
Pour about 500 mL (2 cups) of WinterProof™ RV Water System Antifreeze into the kitchen and bathroom sinks and the shower or tub drains. Clean up any spilled antifreeze. It is normal for the product to become ‘slushy’ and freeze in sub-zero temperatures, but it will not damage the system.
